Mike M.'s octo eating a crab

Mike M. has contributed an image of his octopus (unidentified), eating an orange crab. According to Mike, I was moving the rocks around this morning, and he shot up to the glass from a rock I had just started to move (I didnâ€™t know he was there). He is eating a little orange crab that had lived for about a week under that rock... Thanks for sharing the great picture!
